📣 New Release: codeanalyzer-java v2.4.1

[rahlk]

codeanalyzer-java v2.4.x brings first-class Neo4j graph output for Java, at parity with the Python and TypeScript analyzers. The graph is a lossless, J-namespaced projection of the analysis IR.

Neo4j graph output (--emit neo4j)

Project the Java analysis to a labeled property graph: a graph.cypher snapshot, or a live Bolt push with --neo4j-uri. All node labels are J-prefixed and relationship types are J_-prefixed (e.g. J_CALLS, J_RESOLVES_TO), so a Java graph can share one database with the Py-namespaced Python graph and the TS one without collisions. The provenance property is _module, matching the siblings.

Lossless projection

• New first-class nodes: JInitializationBlock, JCrudOperation, JCrudQuery, JComment, with their containment and call-site edges.
• Every previously-dropped scalar is now carried: file_path, default_value, argument_expr, parameter and variable columns, docstrings, J_CALLS source and destination kinds, and more.
• The scoped wipe and orphan prune follow the new containment edges, so incremental and full-run pushes stay consistent.

Schema contract and config

• --emit schema writes schema.neo4j.json (node labels, relationships, constraints, indexes). Conformance test passes 3/3 (16 node labels, 20 relationship types, 15 constraints).
• Neo4j connection reads NEO4J_URI, NEO4J_USERNAME, NEO4J_PASSWORD, NEO4J_DATABASE when flags are omitted (flag > env > default).

Driver-free Bolt seam and native image

• The fat jar bundles the Neo4j driver, so the live Bolt push works.
• The driver is loaded reflectively, so the GraalVM native image never references it statically and falls back to writing graph.cypher.
• The native image now ships JavaParser AST reflection metadata, so it can analyze real projects (was failing on every parse).

v2.4.1

Follow-up fixes to the lossless field, import, and call-graph projection, plus a build fix that resolves the project path to absolute and surfaces empty-build failures.
